Airglow over Cadillac Mountain - Crop

On July 26, 2014, Matt Pollock and I captured a spherical panorama of green airglow and the Milky Way over Bar Harbor from Cadillac Mountain in Acadia National Park, Maine. This is a crop of the panorama. Cassiopeia can be seen in the left side of the Milky Way arch. Vega can be seen overhead, it is part of the summer triangle along with Deneb and Altair.
